Abstract: A motor comprises a stator, heatsinks, a rotor and a heat-dissipation device. The stator has a hollow potion, a coil portion and a housing portion having a first surface, a second surface and sidewalls. The hollow portion is penetrated through the housing portion. The coil portion is disposed between the hollow portion and the housing portion. The heatsinks are respectively disposed on different sidewalls. The heat-dissipation device comprises a wind-guiding cover and a first fan. The wind-guiding cover comprises a wind-guiding main board and wind-guiding lateral boards. The wind-guiding main board is disposed adjacent to the second surface. The wind-guiding lateral boards are vertically extended from different lateral edges of the wind-guiding main board towards the same direction. Each wind-guiding lateral board is disposed corresponding to one of the heatsinks, and at least one of the wind-guiding lateral boards has a hole. The first fan is received by the hole.
